pedar Systems

The pedar^® system* measures the interaction between foot, shoe and ground, by inserting a sensor insole into the shoe.

Sensor insoles of various sizes (length and width) can be connected by cable to an electronic box, which sends the data to a computer via Bluetooth^® telemetry. The insoles are made of capacitive sensors, which are calibrated and guarantee high repeatability, and also elasticity to conform well to the three-dimensional surface of the feet. The client puts the sensor insoles inside his shoes then the measurement gets started from computer and the client can walks some step until the measurement gets stopped.

The transmitted data can be observed in real time on the screen, and afterwards there can be made an analysis or just a calculation via a pedar^® report.

Technical data for the pedar^®-xf analyser:

• Sensor connection: 2 x 99 sensors (for insoles)
• Scanning speed: 20,000 sensors/second
• Start/stop measurement: cable with switch
• Connection to PC: fiber optic and Bluetooth^® telemetry system
• Optional synchronisation: in and output (fiber optic)
• Data storage: 2 GB SD card
• Power source: rechargeable NIMh battery
• Operating system: current Windows OS

Technical data for the pedar^® insoles:

• Shoe size: 22 to 49 (European), 3 widths
• Thickness: 1.9 mm (min. 1 mm)
• Number of sensors: 85 - 99
• Pressure range: 15 - 600 kPa or 30 - 1,200 kPa
• Hysteresis: < 7 %
• Resolution: 2.5 or 5 kPa
• Offset temperature drift: < 0.5 kPa/K
• Minimal bending radius: 20 mm

Download here the pedar insole catalogue to see the insole sizes and the schematic drawing of each sensor insole. Please notice that one insole size covers two foot sizes.

pedar^® pad

The pedar^® pad is a highly elastic sensor for measurements on the dorsal side of the foot inside the shoe. It can be combined with pedar^® insoles for simultaneous measurement of the plantar and the dorsal aspect of the foot to monitor the shoe-fit.

Technical data for the pedar^® pad:
• Number of sensors: 56 (7 x 8)
• Size of one sensor: 10 x 20 mm²
• Sensor area: 70 x 160 mm²
• Pressure range: 15.0 - 600.0 kPa
• Sensor resolution: 0.5 sensor/cm²

pedar^® sync box (wired)

• Allows wired connection of sync in and out ports of the pedar^® with other systems
• Fiber optic connection from pedar^® analyzer to pedar^® sync box
• TTL input and output of the pedar^® sync ports provided at LEMO connector of the pedar^® sync box and included connection cable
• Availability of pedar^® sync option depends on the selected pedar^® software

pedar^® wireless sync-option

• Consists of 2 small transceiver units
• One transceiver unit is directly connected to the pedar^® analyzer and the second unit stays with the person controlling the measurement
• Allows wireless start of the data acquisition in memory mode of pedar^® system
• Transmits first sync-out pulse of pedar^® at the start of the measurement wireless from pedar^® unit to the receiver unit
• Receiver unit provides TTL output of sync out pulse after the start of the pedar^® at LEMO connector (and included connection cable) for connection with other systems
• Sync out pulse is also displayed by an extra-large LED (in a separate housing) for recording by a video system
• Availability of pedar^® sync option depends on the selected pedar^® software

* Important note for users inside the EC: The pedar^® system is not certified as a medical device according to 93/42/EEC.
